# 1 / 4 Mile ET Calculator

Given below is the 1 / 4 mile elapsed time calculator to calculate 1 / 4 mile ET from horsepower. 1/4 mile or quarter mile is a drag race, a type of motor racing in which the vehicle compete to be first to cross a finish line. (i.e) from starting point to end line. It is done over a measured distance of about 0.40 km track. Here, 1 / 4 mile ET calculator helps you to find the elapsed time for the given vehicle's weight with flywheel horsepower or wheel horsepower.

## Calculate 1 / 4 Mile ET from Horsepower

Given below is the 1 / 4 mile elapsed time calculator to calculate 1 / 4 mile ET from horsepower. 1/4 mile or quarter mile is a drag race, a type of motor racing in which the vehicle compete to be first to cross a finish line. (i.e) from starting point to end line. It is done over a measured distance of about 0.40 km track. Here, 1 / 4 mile ET calculator helps you to find the elapsed time for the given vehicle's weight with flywheel horsepower or wheel horsepower.

#### Formula:

t = 5.825 × ( w / h )0.3333333 f = 5.825 × ( w / (e×0.854) )0.3333333) Where, h = Wheel Horsepower e = Flywheel Horsepower w = Weight of Vehicle t = 1/4 Mile ET for Wheel Horsepower f = 1/4 Mile ET for Flywheel Horsepower

#### Example

Calculate quarter mile elapsed time (ET) of a car that weighs 2900 kgs with wheel horsepower as 295.
1 / 4 Mile ET = 5.825×( 2900 / 295 )0.3333333
= 12.4783 .
